Productivity Index (PI)

The PI represents one point on an inflow performance curve (IPR) and is defined as the well flow in barrels per day per psi pressure drop.

Productivity Index

The continuous production capacity of a PI is a measure of rate (MSCFD) divided by the pressure drop to generate the flow rate

(PSI). Index is MSCFD/PSI or Barrels per day per PSI.

Productivity Index (PI)

“Productivity index” means the daily production of oil in barrels per unit pressure differential between the static reservoir pressure and the stabilized flowing pressure during flow at a stated rate.
